:6. Claims. (Cl. 206-46) This invention relates to'pacKages and more especially to that type ofpa'ckages which lends itself to the preservation and exhibitionof articles or products likely to deteriorate when stored in contact with the atmosphere. It is an object of this invention to'improve packages of this kind'in such'manner as to enable them to protect" the goods enclosed therein againstdeleterious atmospheric action.

The sheets "of plastic orfcellulose materials utilized up to the present for packaging in general, and moreparticularly those that lend themselves readily to conformation such as the sheets of cellulose acetate" or equivalent plastic materials, employed for the preservation of perishable products, such as chemical, pharmaceutic" preparations, food and other products, inv'o1ves"'the disadvantage of not being moisture pro'of' and therefore being-incapable ofeflicientlyprotecting the products they contain.

According to my inventionyin orderxto obtain a moistureproof wrapper with sheets of cellulose acetate (Or equivalent plastic materials) formed with cup-shaped depressions intendedtocontain the products to be packaged,'two sheets of plastic: material are formed with cup-shaped'depressions.

and cemented together by means of.a:m oisture proof binder'with the cups" ofonetsheetnested in the cups of the'other sheet. This" cementing together of the two sheets maybe effected: be-i fore or after the goods to be packaged have been deposited in the depressions, which may then be sealed by means of a pair of similarly cemented sheets; either plane or also formed with cupshaped depressions.

The moistureproof binder employed may be varnish or other relatively inelastic material, sinceit-is not required to conform to the contour of the packaged product.

Other characteristicsand advantages of my present invention will-moreover appear in the description which is about to follow and from the examination of the accompanying drawing on'which have been represented diagrammatically, and merely as-examples, various embodiments of my invention.

In the drawings, Figs; 1 to 4 are'cross-sections of four packings of different configurationwhich embod my invention.

Referring to the drawing and first to Fig. 1, l and 2 are the bottoms of cup-shaped depressions formed in two superposed sheets of plastic material, for instance cellulose acetate. 3, 3 are the Side walls of the depressions in these sheets. Two adjoining depressions form a rece'ptacle for 'an -article to be packaged, as indicatedatl. Thisreceptacle is nested ina similar, somewhat larger receptacle-"formed in 'two sheets of similar material, i -and 5 being the "bottom of the largerreceptacle and 6;6 being its side walls. it, 8 are flat sections of the inner sheets which= surround the inner receptacle, while 9, 9 are flat sections surrounding theouter receptacle. Thesidewallsfi, 6 of the outer receptacle are materially higher, than the side walls, 3,3 of the" inner receptacle and consequently, while the flat portions surrounding-the receptacles are closely adjoined, 'the bottoms' 4; 5 of the "outer receptacle are spaced from the bottoms l, 2 andthe sidewalls 6 of the outerfrom the side walls 3 of "the inner receptacle, forming an all-around air cushion between them. I A layer 30 of a moisturepr'oof adhesivevarnish covers *the inner faces of the outer sheets land E-an'd" cements them together with the inner sheets land 2 at their contacting flat sections 8 and 9. "Theflat sections 8, 8 of the inner sheets are also cemented together by an adhesive which preferably also is moistureproof.

In the package shown in Fig. 2 only the cup bottoms l2, is of the outer and inner sheets are spaced from" each other, while their" side walls l4, l5 are in contact and connected by the glue layer I6that also 'cements'th'eir'flatportions I1, l8 "together.

"Thai-package shown inFig. 3'also has two outer and twoinner sheets for-med with depressionsnestedone in'the other. Howeverhere the depressions 'formed in the-inner sheets are not pressions I 0, I iihavea rectangular cross section,

the inner ones II "have afrusto-conical crosssection. I

'In'the package of Fig. 4- one of the outer sheets 20"is-flat, the other-'2! isformed with large depressions having outwardly curved bottoms 22 Of the inner sheets the'one 23 adjoining the fiat outer sheet 20 is formed with'lowbulging portions which project into themouths of the cup-shaped depressions 25 ofthe other inner sheet 26.

'Iir all th'e figurespas"describedwithreference to Fig. 1, the moistureproof varnish layer 30 covers the inner surfaces of the outer sheets, but this is not a condition.

I wish it to be understood that I do not desire to be limited to the exact details shown and described, for obvious modifications will occur to a person skilled in the art.

each said outer sheet having fiat portions sealed to the flat portions of the adjacent inner sheet by said binder material and intervening portions spaced from the opposing convoluted portions of said adjacent inner sheet, and said layer of binder material being in spaced relation to one of said sheets of each pair in the portions thereof intermediate said flat portions.

2. A moistureproof package comprising two pairs of sheets of non-moistureproof plastic packaging material, each pair comprising an inner sheet and an outer sheet, each inner sheet having a central portion conforming closely to the contour of a product enclosed by the package and a flat peripheral portion extending entirely around said central portion and adapted to sealingly engage the fiat peripheral portion of the other inner sheet, and a layer of moistureproof,

relatively inelastic binder material between each pair of sheets, each said outer sheet having a flat peripheral portion sealed to the fiat peripheral portion of the adjacent inner sheet by said binder material, and a central portion spaced from the central portion of the adjacent inner sheet, so. that the moistureproof material between said central portions is not required to conform to the contour of the product. I

3. A moistureproof package comprising two pairs of sheets of non-moistureproof plastic packaging material, each pair comprising an inner sheet and an outer sheet, each innerv sheet having a central portion conforming closely to the contour of a product enclosed by the package and a flat peripheral portion extending entirely around said central portion and adapted to sealingly engage the fiat peripheral portion of the other inner sheet, each outer sheet having a layer of moistureproof, relatively inelastic binder material on its surface adjacent the inner sheet, each said outer sheet having a flat peripheral portion sealed to the flat peripheral portion of the adjacent inner sheet by said binder mate rial, and a central portion spaced from the central portion of the adjacent inner sheet so that the moistureproof material on said central portion of the outer sheet is not required to conform to the contour of the product.

4. A moistureproof package comprising two pairs of sheets of non-moistureproof plastic packaging material, each pair comprising an inner sheet and an outer sheet, at least one inner sheet having a central cup-shaped depression to receive a product enclosed by the package and a flat peripheral portion adapted to sealingly engage an opposing flat portion of the other inner sheet, and a layer of moistureproof, relatively inelastic binder material between each pair of sheets, each said outer sheet having a flat peripheral portion sealed to the fiat peripheral portion of the adjacent inner sheet by said binder material, and each outer sheet having adjacent each depression in its associated inner sheet a central cup-shaped depression deeper than the depression, in the adjacent inner sheet so that the bottoms of the depressions are spaced from each other and the moistureproof material between said bottoms is effective to protect said inner depression without conforming thereto.

5. A moistureproof package comprising two pairs of sheets of non-moistureproof plastic packaging material, each pair comprising an inner sheet and an outer sheet, each inner sheet having a central cup-shaped depression to receive a product and a flat peripheral portion adapted to sealingly engage an opposing flat peripheral portion of the other inner sheet, each outer sheet having a layer of moistureproof, relatively inelastic binder material on its surface adjacent the inner sheet, each said outer sheet having a flat peripheral portion sealed to the flat peripheral portion of the adjacent inner sheet by said binder material, and a central cupshaped depression deeper and wider than the depression in the adjacent inner sheet so that the depressions are spaced from each other and the moistureproof material between the depressions is efiective to protect the inner depression from moisture without conforming to its contour.

6. A moistureproof package comprising two pairs of sheets of non-moistureproof plastic packaging material, each pair comprising an inner sheet and an outer sheet, each inner sheet having a central portion conforming closel to the contour of a product enclosed by the package and a flat peripheral portion extending entirely around said central portion and adapted to sealingly engage the flat peripheral portion of the other inner sheet, each outer sheet having a layer of moistureproof varnish on its surface adjacent the inner sheet, each said outer sheet having a fiat peripheral portion sealed to the flat peripheral portion of the adjacent inner sheet by said varnish, and a central portion spaced from the central portion of the adjacent inner sheet so that the varnish on said central portion of the outer sheet is not required to conform to the contour of the product.
